RESUMO
OBJECTIVE: Ferulic acid (FA) is a promising nutraceutical molecule which exhibits antioxidant and anti-inflammatory properties, but it suffers from poor solubility and bioavailability. In the presented study, FA nanoemulsions were prepared to potentiate the therapeutic efficacy of FA in prevention of gastric ulcer. METHODS: FA nanoemulsions were prepared, pharmaceutically characterized, and the selected nanoemusion was tested for its ulcer-ameliorative properties in rats after induction of gastric ulcer using ethanol, by examination of stomach tissues, assessment of serum IL-1ß and TNF-α, assessment of nitric oxide, prostaglandin E2, glutathione, catalase and thiobarbituric acid reactive substance in stomach homogenates, as well as histological and immunohistochemical evaluation. RESULTS: Results revealed that the selected FA nanoemulsion showed a particle size of 90.43 nm, sustained release of FA for 8 h, and better in vitro anti-inflammatory properties than FA. Moreover, FA nanoemulsion exhibited significantly better anti-inflammatory and antioxidant properties in vivo, and the gastric tissue treated with FA nanoemulsion was comparable to the normal control upon histological and immunohistochemical evaluation. CONCLUSION: Findings suggest that the prepared ferulic acid nanoemulsion is an ideal anti-ulcer system, which is worthy of further investigations.

Progressive fibrotic interstitial lung diseases (ILDs) are characterised by major reductions in quality of life and survival and have similarities to certain malignancies. However, palliative care expertise is conspicuously inaccessible to many patients with ILD. Unmet patient and caregiver needs include effective pharmacological and psychosocial interventions to improve quality of life throughout the disease course, sensitive advanced care planning, and timely patient-centred end-of-life care. The incorrect perception that palliative care is synonymous with end-of-life care, with no role earlier in the course of ILD, has created a culture of neglect. Interventions that aim to improve life expectancy are often prioritised without rigorous assessment of the individual's health and psychosocial needs, thereby inadvertently reducing quality of life. As in malignant disorders, radical interventions to slow disease progression and palliative measures to improve quality of life should both be prioritised. Efficient patient-centred models of palliative care must be validated, taking into account religious and cultural differences, as well as variability of resources. Effective implementation of palliative care for ILD will require multidisciplinary participation from clinicians, specialist nurses, psychologists, social workers, and, in some countries, non-governmental faith and community-based organisations with access to palliative care expertise.

BACKGROUND: Impeccable assessment of symptoms is central to palliative care (PC) practice. OBJECTIVES: The study objectives are (1) to test the validity of the Arabic Questionnaire for Symptom Assessment (AQSA) as a self-administered (SA) tool for assessing the severity of the listed symptoms among PC patients and (2) to test the validity of AQSA when completed by a proxy. METHODS: The AQSA is a tool for assessing the severity of 11 symptoms in addition to the overall suffering experience on a 0 to 10 numeric scale. Symptom scores on the SA AQSA were compared to scores obtained through interviews with patients. The same procedure was repeated with patients' sitters to explore the validity of using the tool for symptom assessment by proxy. RESULTS: The study involved 107 pairs (a patient and a sitter, each) with a mean age of 46.3 years (females 59.8%) for patients and 35.9 years (females 65.7%) for sitters. The correlation coefficient ( r) for agreement between SA and interview-based (IB) scores for patients ranged from .65 ( P < .0001) for drowsiness to .86 ( P < .0001) for pain. The SA AQSA showed positive correlation between sitters' and patients' scores, with r ranging from .28 ( P = .004) for depression to .62 ( P ≤ .0001) for vomiting. CONCLUSIONS: The strong positive correlation between SA and IB AQSA indicates that the former is a valid tool. When the SA AQSA is used by proxy, it showed moderate to strong positive correlation with patients' actual scores for most of the symptoms.

Chromium (Cr) is used in many industries and it is widely distributed in the environment. Exposure to Cr dust has been reported among workers at these industries. Beside its hazardous effects on the lungs, brain injury could be induced, as the absorption of substances through the nasal membrane has been found to provide them a direct delivery to the brain. We investigated the distribution and the effects of Cr in both brain and lung following the intranasal instillation of potassium dichromate (inPDC) in rats. Simultaneously, we used the common intraperitoneal (ipPDC) rat model of acute Cr-toxicity for comparison. Thirty male Wistar rats were randomly allocated into five groups (n = 6); each received a single dose of saline, ipPDC (15 mg/kg), or inPDC in three dose levels: 0.5, 1, or 2 mg/kg. Locomotor activity was assessed before and 24 h after PDC administration, then, the lungs and brain were collected for biochemical, histopathological, and immunohistochemical investigations. Treatment of rats with ipPDC resulted in a recognition of 36% and 31% of the injected dose of Cr in the brain and lung tissues, respectively. In inPDC-treated rats, targeting the brain by Cr was increased in a dose-dependent manner to reach 46% of the instilled dose in the group treated with the highest dose. Moreover, only this high dose of inPDC resulted in a delivery of a significant concentration of Cr, which represented 42% of the instilled dose, to the lungs. The uppermost alteration in the rats locomotor activity as well as in the brain and lung histopathological features and contents of oxidative stress biomarkers, interleukin-1ß (IL-1ß), phosphorylated protein kinase B (PKB), and cyclooxygenase 2 (COX-2) were observed in the rats treated with inPDC (2 mg/kg). The findings revealed that these toxic manifestations were directly proportional to the delivered concentration of Cr to the tissue. In conclusion, the study showed that a comparably higher concentrations of Cr and more elevated levels of oxidative stress and inflammatory markers were observed in brain and lung tissues of rats subjected to inPDC in a dose that is just 0.13 that of ipPDC dose commonly used in Cr-induced toxicity studies. Therefore, the study suggests a high risk of brain-targeting injury among individuals environmentally or occupationally exposed to Cr dust, even in low doses, and an additional risk of lung injury with higher Cr concentrations. Moreover, the study introduces inPDC (2 mg/kg)-instillation as a new experimental animal model suitable to study the acute brain and lung toxicities induced by intranasal exposure to Cr compounds.

BACKGROUND: Maintaining maternal and neonatal tetanus (MNT) elimination status in Egypt requires continued strengthening of routine tetanus toxoid (TT) immunization services for pregnant women. OBJECTIVES: To measure the frequency rate of TT vaccination among women attending the well-baby clinic at the El-Darb El-Ahmar primary healthcare center in Cairo governorate and to identify different associated factors. PARTICIPANTS AND METHODS: This was a cross sectional study that targeted 277 mothers who attended the well-baby clinic at the El-Darb El-Ahmar primary healthcare center. Mothers were interviewed by a questionnaire inquiring about their sociodemographic characteristics, obstetric history, details of the last pregnancy, TT vaccination status and knowledge of the TT vaccine, and MNT disease. RESULTS: The results showed that 60.6% had taken all required doses of TT vaccine and 42.6% of the mothers studied were fully protected against MNT in their last birth. The rate of vaccination was found to be affected by mothers' socioeconomic level, education level, place of receiving antenatal care, health education about importance of TT vaccine, knowledge of mothers about NT disease and TT vaccine and the source of this knowledge.

CONTEXT AND OBJECTIVES: The use of complementary and traditional medicine (CTM ) in Middle Eastern countries is widespread, including among patients with cancer. Perspectives of oncology healthcare professionals (HCPs) in this region regarding the integration of CTM within conventional supportive cancer care were explored. METHODS: An 11-item questionnaire with an open-ended question asking respondents to comment about the integration of CTM within supportive cancer care was sent to Middle Eastern oncology HCPs, using snowball sampling methodology. The narratives provided were examined using thematic analysis. RESULTS: A total of 339 oncology HCPs completed and returned the study tool (80.3 % response rate ), of which 178 from 15 Middle Eastern countries responded to the open-ended question. The majority of respondents are in favor of the integration of CTM within supportive cancer care, though ideas on how this should be implemented varied. Thematic analysis identified multifactorial barriers to integration, which focused on HCPs' perspectives (e.g., a lack of knowledge and training; a skeptical approach to CTM), attitudes of patients and caregivers (e.g., unrealistic expectations regarding the outcomes of CTM treatments) and HCP-patient communication. In order to overcome these barriers, respondents suggested education and training programs for oncology HCPs which would focus on improving patients' quality-of-life-related outcomes. CONCLUSIONS: Middle Eastern oncology HCPs support the integration of CTM within supportive cancer care, while recognizing the need for education and training in this field. A better understanding of CTM would provide the knowledge and skills which would promote a non-judgmental, evidence-based approach, fostering better communication with patients.

INTRODUCTION: In this multinational Middle-Eastern study, we assessed health-care providers' (HCPs) perspectives on their patients' use of complementary and traditional medicine (CTM) and identified the leading barriers to CTM integration in supportive cancer care. METHODS: A 17-item questionnaire was developed and administered to HCPs attending palliative medicine workshops conducted across the Middle East by the Middle East Cancer Consortium. RESULTS: 339 HCPs from 16 countries across the Middle East completed the questionnaire (80.3 % response rate). Respondents perceived their patients' reasons for CTM use primarily in the context of cancer cure (63 %) and quality of life (QOL) improvement (57 %). Expectation regarding CTM's role in cancer cure/survival was more pronounced in Turkey, Jordan, the Palestinian Authority, and the Persian Gulf area. In contrast, the expectation that CTM would improve QOL was more emphasized in Israel. A mid-position between the cure/survival and QOL poles was observed in Cyprus, Lebanon, and the North African countries. Leading barriers to CTM integration in supportive cancer care included oncologists' skepticism and a gap between patients' expectations and HCP's objectives. Respondents' leading recommendation to HCPs was to communicate integrative care emphasizing well-being and improved functioning in accordance with their patients' health beliefs. CONCLUSION: CTM integration in supportive cancer care can be facilitated by implementing a platform for Middle Eastern clinical collaborations. HCPs' expectations and experiences with CTM have been positive in the oncology setting. These data need to be corroborated with information of patients' expectations on the provision of CTM over all phases of the oncology treatment.

Drinking water from bottle-less coolers may pose some public health risks to consumers due to either chemical or microbiological contamination. This study was carried out aiming at assessing the quality of water dispensed from some public coolers in order to determine its compliance with the drinking water standards (Egyptian, EPA) and with the WHO guidelines. Twenty water coolers were selected randomly from different districts. Water samples were collected thrice from these coolers and once from the mains supplying the coolers. Results of analysis of these samples revealed that 85% of water coolers were containing <0.5 mg/l free residual chlorine, 65% were containing lead higher than 0.01mg/l, and 55% were containing magnesium hardness higher than 150 mg/l. As for the biological contamination, 15% of the coolers were contaminated with Cryptosporidium parvum, 15% were containing total coliform group of bacteria, 5 % gave positive thermotolerent coliform test and 5% gave positive Streptococcus fecalis test. The study concluded that such contamination might be from failure to thoroughly clean the coolers on a regular basis. Consequently, the study recommends proper installation of the cooler, a maintenance agreement with the cooler supplier, testing cooler water at regular intervals by the Ministry of Health representatives, and -if possible- replacing these types of coolers with those with a water purification system.
RESUMO
The few palliative care programs available to date in Saudi Arabia are largely hospital-based. Subacute palliative care models have not been developed yet. This retrospective review was conducted to assess the patterns and outcomes of hospital-based palliative care unit admissions in the absence of subacute palliative care models. We reviewed 759 eligible palliative care unit admissions related to 629 cancer patients during a 4-year period. Of all admissions, 66% were hospitalized through the emergency room. The average hospital stay was 24 days. The majority (86%) of patients died in-hospital. These results suggest that end-of-life quality indicators are unlikely to improve depending on hospital-based palliative care models only. To improve palliative care services in Saudi Arabia, other subacute models may need to be considered.
